LOOSE-LEAF BINDER.

To all whom t may concern:

Be it known that I, WALTER CARL AKANs, a citizen of the United States of America, residing at Birmingham, in the county oi Jefferson and State of Alabama, have invented certain new and useful Improvements in Loose-Leafl Binders, of which the following is a specification.

My invention relates to loose leaf binders and has for itsl object to devise a very simple and strong binding means capable of adjustment to bind a substantially lesser or greater number of leaves than that for which the binding is more especially designed. This feature has particular advantage as applied to loose leaf record books, permitting a considerable portion of the leaves to be removed for purposes of being written up or otherwise used and the binding adjusted to tightly and firmly hold the remaining leaves in place. Moreover, if for any reason, it should be desired to incorporate additional leaves in the record book beyond that for which the binder is designed, it can be extended to accommodate these additional leaves. My binder comprises telesco ie post sections which are carried by adjustable binding plates relatively movable toward and from each other by means of a trans- `versely disposed reversely threaded screw.

The adjustment of the binding plates is ob tained by mounting them upon a rigid backing plate and providing an oblique pin and socket connection between the binding plates and backing late which causes them to shift both lateral y and longitudinally of the backing plate, which is itself riveted or made fast to the back bone. The backing plate is preferably narrower than the back bone and its width corresponds with the normal spacing of the binding plates, which latter however can be adjusted to bring them within or beyond the side edges of the plate, according to the number of sheets to be bound.

My invention also involves the provision of a simple means of preventing the unauthorized tampering with the book.

My invention also comprises the novel details of construction and arrangements of parts which in their preferred embodiment are illustrated in the accompanying drawings, in which Figure 1 is a plan view of the back bone,

backing plate and binding plates in their contracted position.

Fig. 2 shows the binding plates in their maximum expanded position.

Fig. 3 is an enlarged cross sectional view taken on the line 3-3 of Fig. 1, and showing the binding plates adjusted to normal position with the adjusting key in place.

Fig. el is a detail view of the key controlled means for the adjusting screw.

Similar reference numerals refer to sin|ilar parts throughout the drawings.

As illustrated, I have shown my invention applied to a record book comprising a back bone l and side boards 2 suitably hinged thereto. Along the center of the back bone I secure by rivets 3 or otherwise a metallic backino' plate 4, which plate stops short of the ends of the back bone and is made substantially narrower in width than the back bone. Mounted upon the backing plate 4 are a pair of adjustable binding plates 5 which are formed of sheet metal and coinprise each a Hat wide base portion 6 and a marginal edge 7 which surrounds all but the inner side edge of each plate. At the center of each plate I rivet or secure an angled bracket 8, which brackets have their upturned ends disposed at the inner edge of each plate and provided with reversely threaded holes to receive the reversely threaded ends of an adjusting screw 10. The leaf binding means comprise posts l1, two of which as shown are made fast to the outer flange of each backing plate and the posts on each backing plate telescope into tubular sleeves 12 on the other backing plate, the length of the sleeve and post being equal to the space between the binding plates when in their most contracted position, z'. e., when their edges abut and form a boXlike body as seen in Fig. 1. When the binding plates are expanded to their extreme positions, as seen in Fig. 2, it will be observed that they have shifted both lengthwise and transversely of the backing plate 4. This motion of the binding plates is obtained by the provision in their bases 6 of slots 13, the slots in each plate being inclined in the same direction and the slots in one plate being disposed at right angles to the slots in the other plate. The backing plate 4 carries four rivet pins 14 which are passed through the slots 13 and have Wide large heads 15 which engage the iop face ot thebaling plates and o ,di the .latter securely to 'the' base 4; While leaving them free for their diagonal sliding Inoveinents relative thereto.

The adjustment of the plates is accomplished by turning the screw 10, which serves either to draw the plates together or spread thenl apart and in such movement the plates are guided byu the rivet `pins 14:. 'lo turn the adjusting screw l provide a key 1G and in a suit-able opening provided in one of the flanges i insert a key guard or lock 17 which is inI line with the unthreaded end 1S oi the screw 10. r[`his end 18 is pro vided with a slot 19 disposed in position to receive the key after the latter has been passed through the gnard'or look 17, which is mounted to rotate in the iange so that when the 'proper key is passed therethrough it can be turned to turn the screw 10 with it.

'lhe leave` 2() oi the book, which are indieated in dotted lines, Fig. 3, are cut` away so as to iit over the binding posts and over the screw 1U and itsbrackets 8.

lt will be observed that in the movements oi the binding plates lengthwise of the backn ing leaves they are always protected by the ends of the back bone, and that in their eX- p'anded position the outer side edges oi' the binding plates entend beyond the vbacking plate i yto the side edges ot' the back bone. The rivet pins may be made fast to any snitable back o1" 'backing plate and, in fact, any equivalent sliding connection between the binding plates and book` may be used which will permit the binding plates to move as described.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is :H

` 1. In a loose leaf binder, a metallic bacio ing plate, binding elements mounted on said` backing plate andadjnstable lengthwise and transversely thereof, pins Connecting said binding'e'lements to theV backing plate, there being slots for said pins which are elongated diagonally 'of the backing plate, and a transverse means for moving said binding members toward and from each other, substantially as'described.
